Improve the reliability of your industrial electrical systems with the Siemens SIRIUS 3RV2021‑4PA10 motor protection circuit breaker. This three‑pole circuit breaker (30–36 A rating) is engineered to deliver consistent, high‑fault performance in demanding environments. Compliant with UK standards and built to last in strict industrial settings, it ensures precise overload and short‑circuit protection while maintaining ease of installation. With screw terminals, DIN‑rail mounting, and a compact footprint, it is the go-to choice for streamlined maintenance and maximum uptime.

What Sets the Siemens Motor Protection Circuit Breaker, 3P Channels Apart?

You’ll benefit from top-tier motor safeguarding thanks to its Class 10 thermal overload and magnetic short‑circuit releases. Rated up to 690 VAC and able to handle fault currents of up to 20 kA (with breaking capacity typically 20 kA at 400V), it balances robust protection with energy efficiency and low power dissipation. The device’s compact size (S0 size, ~97 × 45 × 91 mm, 0.387 kg) makes it ideal for both new installations and retrofit upgrades across UK industrial sectors.

Standout Features and Benefits Include
