Product details

Three poles, 50 A continuous at 40 °C, with a thermal-magnetic trip curve that holds to 50 A up through 50 °C and derates to 45 A at 70 °C — so in a warm enclosure you lose 5 A of headroom, which matters when sizing for a continuous load near the limit. The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. No communication function onboard; this is a standalone protection device, not a smart breaker.

Panel integration and physical fit

Depth of 70 mm leaves room behind the gland plate for cable bends.

Frequently asked questions

Where can I buy 3VA1150-5EF32-0CH0 and get current pricing?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 3VA1150-5EF32-0CH0 drop into a panel specified around 3VA1110-5EF32-0AM0 without rewiring?

The 3VA1150-5EF32-0CH0 shares the same 3-pole SENTRON 3VA platform and identical mounting footprint as the 3VA1110-5EF32-0AM0 — same width (76.2 mm), same depth (70 mm), same height (130 mm). The difference is the frame rating: the 1150 is a 50 A breaker, while the 1110 is a lower-current variant. Terminal layout and bus connections are identical; a direct swap is possible provided the ampacity matches the circuit.

What are the interrupting ratings of 3VA1150-5EF32-0CH0 at different voltages?

187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V.
