What this SIRIUS breaker does in a panel
The gL/gG fuse coordination at 400 V is 32 A, dropping to 25 A at 690 V — that tells you the backup fuse size if you need type 2 coordination with the downstream contactor. Motor horsepower assignments are listed for common voltages: 1 hp at 200/208 V and 220/230 V, 3 hp at 460/480 V and 575/600 V, and 0.5 hp at 230 V. That 3 hp at 480 V is the typical sizing for a small pump or conveyor motor on a 480 V line. Switching frequency is limited to 15 operations per hour under AC-3 duty — fine for a start/stop cycle on a machine that runs minutes at a time, but not for a rapid-reversing application like a jog station.
Depth is 97 mm, height 106 mm. That 50 mm vertical gap matters when you are stacking breakers in a multi-tier enclosure; the hot air from the lower unit needs room to rise. No ground-fault or phase-failure detection built in — if you need those, you add a separate monitoring relay or choose a SIRIUS 3RV2 with the optional module.
