Compact, High Performance Fuse is Optimal for Intrinsically Safe Applications

Schurter's Universal Modular fuse, UMT-H, offers a 1500 A breaking capacity at rated voltages of 277 VAC / 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval. This time-lag fuse provides overcurrent and short circuit protection in various industrial control applications, including intrinsically safe applications.

The "intrinsic safety" method is one of the most common techniques used for achieving safety protection with lower voltage or power equipment. This method restricts the available electrical and thermal energy in a system so that ignition of a hazardous atmosphere (such as explosive gas, dust, or electrical arcing) cannot occur. The UMT-H's high breaking capacity of 1500 A, plus the >10 mm spacing between end caps, combined with the ability to be impermeable to conformal coating makes the fuse suitable for use in such intrinsically safe applications.

The UMT-H fuse is available in a total of 19 rated currents between 160 mA and 10 A at voltages up to 277 VAC and 250 VDC. The UMT-H measures at 5.3 x 16 mm, which is a smaller alternative to the classic cylindrically-shaped cartridge fuses (e.g. 5 x 20 mm). The smaller footprint saves valuable board space, allowing for further downsizing of equipment. With its square design, the UMT-H is also suited for more cost-effective, automated assembly. The high breaking capacity fuse meets the IEC 60127-7/1, UL 248-14 and CSA C22.2 standards along with its VDE and UL approvals. Additional applications include power supplies, electromobility, medical and telecommunication applications as well as 277 VAC utility-connected equipment.

Features/benefits:

- Certification according to IEC 60127-7/1, UL 248-14, CSA C22.2 no. 248.14
- High breaking capacity (H) of 1500 A at rated voltage
- High rated voltages up to 277 VAC / 250 VDC
- 19 rated currents from 160 mA to 10 A
- Time-lag (T) characteristics
- Optimal suited for automated assembling because of square design
- Suitable for intrinsically safe applications

Schurter is expanding its range of block filters for single-phase systems with its new FMAB NEO series. This range of single-phase filters combines a compact design with a high level of performance. The use of large X capacitors permits high symmetrical attenuation.

The new FMAB NEO filter series boasts a compact design combined with high performance. All versions come with large X capacitors, which ensure high symmetrical attenuation in the lower frequency range. Symmetrical interferences can occur because of phase-angle controllers or semi-conductor relays, for example. When the power semiconductors switch, they generate interference currents between the phase conductor and the neutral conductor. These are known as symmetrical interferences, which the X capacitors positioned between these conductors can help reduce effectively.

The filters in the new series have a shiny steel housing with a closed filter base. The filter is thus effectively and completely shielded, no matter how it is mounted. The filter series is particularly suitable for equipment with high symmetrical interferences, such as devices with semiconductors that control high-power equipment such as professional coffee machines, devices with water heaters, and all types of industry electronics. The compact filters are also suitable for medical equipment and household appliances.

The filter series is available with plug-in connections or thread bolts (30 A version). A version with wire connection is also available. They have a metal flange for easy screw-on mounting on the housing.

The series of devices is designed for current levels from 1 A to 30 A at 250 VAC according to IEC and UL standards. It has ENEC and cURus approvals and is suited for applications according to IEC 60950. Versions are available with small leakage currents <80 μA (M80) or without leakage current <5 μA (M5) for medical equipment according to IEC/UL 60601-1.

Technical Data:
- 250 VAC single-phase block filter
- Single-stage filter with large X-capacitors
- Excellent symmetrical attenuation
- Filter available ins standard or medical M5 / M80 version
- Rated currents: 1, 3, 4, 6, 8, 10, 12, 16, 20, 30A (ENEC / UL / CSA) at 40°C
- Chassis: Screw-on mounting, from top
- Quick connect terminals 1 – 20A, nut and bolt 30A, optional wire leads

Application:
- For applications with high symmetrical interferences
- Industrial applications
- Household appliances
- Datacom equipment
- Medical equipment
