Description
RCCB, 4-pole, type B, short- time delayed, In: 25 A, 300 mA, Un AC: 400 V
The Siemens 5SM3642-4 RCCB is a four-pole Residual Current Circuit Breaker designed to provide protection against electric shock and control electrical circuits. It has a Type B classification, which means it can detect both alternating and pulsating direct currents.
The RCCB is configured with a short-time delayed feature, which means it is equipped with a delay mechanism to allow for brief current surges or transients without tripping the circuit. This delay is particularly useful in applications where temporary current spikes are expected, such as when starting motors or inductive loads.
The 5SM3642-4 RCCB has a rated input current of 25 A, meaning it can handle up to 25 amps of incoming electrical current. Additionally, it has a sensitivity of 300 mA, which means it can detect and interrupt electrical circuits when the residual current exceeds this threshold.
This particular RCCB is designed for use in alternating current (AC) systems with a voltage rating of 400 volts. It is manufactured by Siemens, a reputable brand known for producing high-quality electrical products.
