TSRG205 - 500A - Neutral Current Sensor

TSRG205 500 Amp Circuit Breaker

When you’re dealing with high amperage, you don’t want to second-guess your protection. The TSRG205 500A circuit breaker is built for jobs where consistent performance matters—plain and simple. It’s a straightforward unit with a compact 8 x 4 x 4 inch footprint, so it won’t fight you during installation. Whether you’re swapping out an older breaker or setting up a new system, it fits into place without turning the job into a headache. This model is also used in systems with ground fault protection, but there’s one thing to keep in mind—neutral current sensors are required for 3-phase 4-wire and 1-phase 3-wire setups. That’s key for proper operation, especially in more sensitive environments. No fluff here. It’s a high-capacity breaker designed to do its job—protect your system and keep things running the way they should.
