Product details

Motor protection breaker, size S00 — 0.9-1.25 A thermal, 16 A magnetic

The Siemens 3RV2011-0KA20-Z W96 is a SIRIUS 3RV2 motor starter protector in size S00, designed for motor branch-circuit protection in control panels. The CLASS 10 thermal overload release trips within 10 seconds at 7.2× rated current, which matches the startup profile of standard AC induction motors — a compressor or small conveyor motor on a 400 V line, for example. The adjustable A-release covers 0.9...1.25 A, and the fixed magnetic short-circuit release (N-release) is set at 16 A, so the breaker clears a bolted fault before the contactor can weld. This unit is packaged in a multi-unit bundle of 8 pieces, which matches the common panel-builder practice of kitting an entire motor control center's worth of breakers on one line item.

Active production — current lifecycle status

RoHS compliance is confirmed since October 1, 2009. No SVHC candidate-list change has triggered an update.

The spring terminals face forward, so wiring access is clear even in dense rows — no need to reach around adjacent devices.

Frequently asked questions

How do I get current pricing and availability for 3RV2011-0KA20-Z W96?

Submit an RFQ through this listing. As a standard stock-class product (class A), pricing and lead time are confirmed at quote time against the current distribution channel.

What is the closest alternative to 3RV2011-0KA20-Z W96 in the SIRIUS family?

Within the SIRIUS 3RV2 size S00 range, the key differentiator is the thermal release range. This variant covers 0.9–1.25 A with a 16 A magnetic release. A sibling with a higher or lower A-release window would change the motor FLA coverage — the mechanical footprint and terminal style are identical across the size S00 platform.

What compliance documentation does Siemens provide for this part?

RoHS compliance is declared effective October 1, 2009. The REACH Article 33 declaration identifies lead (CAS 7439-92-1) above 0.1% w/w. Export control classification is AL: N / ECCN: N — no license required for standard industrial use.
