如果已使用 MCB 或 RCD，是否需要绝缘监控继电器？

如果系统无接地故障保护，则需要绝缘监控继电器防止其发生电气故障。在这种系统中发生的接地故障所释放的能量不足以触发 MCB（微型断路器）或 RCD（剩余电流设备）。

【英文介绍】

CM-IWS - Insulation monitoring relay

The CM-IWS series relay monitors insulation resistance and is configured to meet application requirements. All devices are available in two different terminal versions: screw connection technology and easy connection technology.

The control power supply voltage is rated 24-240V AC/DC

The device monitors control circuits (single-phase) and power circuits (3-phase)

A measuring range of 1-100 kΩ

Precisely adjust the threshold in 1kΩ increments

Interrupted wire detection

3 operating status LED indicators

1 c/o (SPDT) contact, closed circuit principle

ABB insulated monitoring relay, 250 V AC /300 V DC maximum induced voltage - 1SVR730660R0100 CM-IWS.1S

Check the insulation resistance in the circuit with this ABB insulation monitoring relay. It detects faults and quickly trips in the event of an electrical hazard, preventing equipment damage. With three LED indicators, you can quickly understand the working status, easy to use. The device monitors systems with voltages up to 250 V AC or 300 V DC for high-load applications.

Characteristics and advantages

• Screw terminal for solid connection

• Compact size 103.7 (L) x 22.5 (W) x 85.6mm (H), suitable for small Spaces

• Weighs only 0.148kg to minimize equipment stress

Apply

• Construction industry

• Solar equipment

• Maritime industry

• IT Systems

Do you need to insulate monitoring relays if you have used MCB or RCD?

If the system has no ground fault protection, the monitoring relay needs to be insulated to prevent electrical failure. A ground fault that occurs in such a system does not release enough energy to trigger an MCB (miniature circuit breaker) or RCD (residual current device).
