With its latest ranges of compact yet versatile timing relays, Moeller Electric now offers convenient and cost-effective timer options covering virtually every control panel and power distribution application.

Special features of the Moeller Electric timer family include models for operation direct from 400V supplies, which are ideal for use in three-phase systems where no neutral is available, models with remote adjustment facilities, and ultra-compact versions just 17.5mm wide, which save valuable space in distribution boards.

Featuring the same design and dimensions as the popular DILEM contactors, DILET timers are well suited for control panel applications. They are available in three types, the DILET 11-30 which is an economical option where an on delay of between 1.5 and 30s is required; the DILET 11-M which also offers an on-delay function, but has ten timing ranges covering 0.5 seconds to 60 hours; and the DILET 70 multi-function relay which offers a choice of eight timing functions as well as the option of adjusting the setting with a remote potentiometer.

DILET timers can be supplied in universal versions for use with AC and DC supplies anywhere in the range 24V to 240V, and for 400V AC operation.

For applications where maximum versatility is required from a compact timing relay, Moeller Electric offers the ETR4 range. Just 22.5mm wide, these DIN-rail mounting units cover times of 0.05s to 100h in ten ranges, and offer a choice of different timing functions. The range offers a basic on-delayed timer, a star-delta timing relay and two multi-function relays, ETR4-69 and ETR4-70 offering eight timing functions. The ETR4-69 has a single changeover output contact, while the ETR4-70 has two changeover contacts and also allows the connection of a potentiometer for remote adjustment.

Both the ETR4-69 and ETR4-70 have an opto-isolated input to allow timing to be initiated from almost any kind of external circuit, and both incorporate LEDs that give a clear indication of current status.

Moeller Electric’s ultra-compact ETR2 timing relays have been specifically designed for use in distribution boards, and are the same size as most miniature circuit breakers. In spite of their small dimensions, they offer a timing range from 0.05s to 100h, and are available in six different versions, including a multi-function model. All ETR2 relays are suitable for use with AC and DC supplies in the range 24V to 240V.

The new KF-series features exceptionally large isolation distances and offers high AC-23A motor ratings.  It covers the range from 16A to 32A and offers disconnect capability of up to 1000V according to IEC 947.  The rotary contact system incorporated in a new type of modular contact block allows high mechanical life expectancy and precise and reliable contact making.

The innovative modular system is both simple and very safe while offering enormous flexibility.  All available modules can be combined, exchanged or added in the field, as can the very precisely working cam-operated auxiliary contacts.  The position of the various modules in relation to each other
can be defined by the user or, if preferred, preassembled in the factory.

* Coupling profile determines pre-closing function of switched 4th pole,
  i.e. contact modules per se are always the same

* Rotating contact movement (instead of classical vertical lifting) allows
  big contact gaps
  high mechanical life expectancy
  very precise movement sequence
  self-cleaning contacts
  forced opening and closing of contacts

* Compact (very shallow) design

* Up to 1000V insulation voltage according to IEC possible

* Lateral drive possible (latching module not in the centre but on left or right hand side)

* Visible contacts (windows) available on request

* Design allows a big variation of terminal markings

* Removal from DIN rail can be done without tool change (screw driver for cross-recessed screws sufficient)

Crydom has combined solid state and mechanical switching
technologies to create a contactor with longer operational life
than standard EMR’s in an industry standard package!

Crydom, global expert in solid state relay technology, introduces a new line of high power Hybrid Solid State Contactors for use in Heating and Lighting applications where Mercury Displacement Relays have previously been applied, and where life cycle constraints limit the use of Definite Purpose Contactors.

crydom_rhp.pdf

Mounting identically to a standard 3 phase DP (Definite Purpose) contactor, and featuring full load life cycle ratings of greater than 2 million operations, the new RHP line includes 3 phase contactor configurations rated at 120, 240, 280 or 600 VAC at 40 or 50 amp load ratings per phase at 65 degrees C ambient temperature. Control voltages of 24, 120 or 220 VAC, and unique logic compatible 5, 12 or 24 VDC input control options are offered. The RHP line is UL and cUL approved and CE certified.

The RHP line incorporates Crydom’s proven Hybrid SSR technology that utilizes contactless Solid State Relay turn on and turn off performance, coupled with the very low on state power dissipation characteristics of contactors, thus eliminating the need for heat sinking. The higher power switching capabilities of the new RHP line means that in those applications where Mercury Displacement Relays are no longer welcome, the OEM manufacturer now has a cost effective alternative available. Similarly, in applications where contactor life cycles are a limiting or maintenance cost concern, the new Crydom RHP Contactor provides significantly longer operational life capability in an identical mounting package.

Crydom Solid State Relays (SSRs) are widely used in applications where controlling different types of motors is necessary. They are used for AC motor speed control, motor reversing, starting motors, soft starting and soft stopping of motors, motor starting switches of both single phase and three phase motors.

Crydom SSRs are also used to control DC motors.  DC relays can be used as a switch, for reversing DC motors, or using PWM (Pulse Width Modulation) for DC motor speed controls.

Only reliable, continuous monitoring of the three-phase supply can ensure  trouble-free and efficient operation of motors, machines and equipment. ABB now offers a comprehensive range of 22.5 mm, within the CM series, to protect sensitive equipment from adverse three-phase voltages. The product range extends from the full protection
multifunction three-phase monitor, CM-MPS, to single-function devices for monitoring single parameters.

The CM-MPS is a multifunction monitoring relay. It monitors all phase parameters including: phase sequence, phase failure, over- and undervoltage and phase unbalance. It is available with or without monitoring of the neutral conductor. Seven devices with a graded scope of functions complete the CM product range. The new devices for three-phase voltage monitoring, CM-PVS and CM-PSS along with the CM-PAS for monitoring phase unbalance, offer functions adapted to the relevant requirements and facilitate the accurate monitoring of three-phase mains.

The characteristics of the three-phase monitors are:
• Phase failure monitoring
• Phase sequence detection*
• Over- and undervoltage monitoring (fixed or adjustable)*
• Adjustable phase unbalance threshold*
• Adjustable delay time, and selectable ON-delay or OFF-delay function*
• Dual-frequency,  50/60 Hz operation
• Powered by the measuring circuit 
• 1 n/o, 1 or 2 c/o  contacts
• LED for status indication
• Wide operating voltage range

*Depends on device type
