SIEMENS 5SV33224 Residual Current Circuit Breaker, Type B, 25 A, 30 mA, 230 V, 1+N, 4 TE, Short-Time Delayed

This SIEMENS residual current circuit breaker stands out with its Type B tripping characteristic, which detects smooth DC residual currents in addition to AC and pulsating DC, making it suitable for circuits with frequency converters or EV charging. The short-time delayed version avoids nuisance tripping from brief current spikes.

Highlights

• Type B RCCB for comprehensive protection against AC, pulsating DC, and smooth DC residual currents
• Rated residual current 30 mA for personal protection
• Short-time delayed tripping to prevent false trips from transient surges
• Compact 4 TE width for space-saving DIN rail installation

In daily use

Install this 2-pole (1+N) RCCB on a DIN rail to protect a 230 V single-phase circuit. It handles rated currents up to 25 A and interrupts residual currents of 30 mA. The screw terminals accept solid conductors from 0.75 to 35 mm² and stranded from 0.75 to 25 mm², ensuring flexible wiring options.
