RCCBs for SMISSLINE TP

The SMISSLINE RCCBs prevent personal injury and damage to property caused by electric current. Use of this circuit breaker is required in various national and international standards for electrical installations. Modern residual current operated circuit breakers respond to small residual currents. Interruption occurs in a fraction of a second even before a hazardous situation for people, animals and property can arise.

• High short-circuit resistance 10kA
• Type A, F and B
• 2- and 4-pole types
• Nominal residual trip currents 10, 30, 100, 300mA
• Snap-on auxiliary switches and signal contacts
• Nominal currents 25, 40, 63A
• Double terminals

F404 B RCCBs offer protection against direct contact and are the correct choice to guarantee maximum operational reliability through early detection of smooth DC residual currents at high frequencies.

Features

• Standard: IEC/EN 61008-1 and EN 62423 for Type B
• High level of system availability due to high surge current withstand capacity of 3 kA (or optionally 5 kA) and 10 ms short-time delay
• Coordination and back-up protection with ABB device

Product details

1. Can be plugged directly onto the socket system
2. Identification marking according to EN 62423. Simple identification of the fields of application via symbols showing the forms of residual current.
3. Reliable recognition of the switching status through red/green position indicating device and position of the switching knob
4. Green LED to monitor the operating condition:
   - RCCB with Type B functionality
   - RCCB only with Type A and Type F functionality

Protection against the effects of sinusoidal alternating and direct pulsating earth fault currents; protection against indirect contacts and additional protection against direct contacts (with IDn=30 mA).

Function: protection against the effects of sinusoidal alternating and direct pulsating earth fault currents, providing the best compromise between safety and continuity in the service thanks to the resistance to unwanted trippings; protection against indirect contacts and additional protection against direct contacts (I∆n=30 mA).

Cutting-edge features: safety, service continuity, compactness, integration. These are the characteristics of the F404 B RCCBs (residual current circuit breakers)
