It's rated 16 A continuous at 40 °C and delivers 75.6 kA interrupting capacity at 240 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream.
At 415 V it's still 52.5 kA, dropping to 32 kA at 440 V and 11.9 kA at 500 V and 690 V. That's a steep derate curve above 240 V — if your system's available fault current at 480 V is, say, 25 kA, this breaker still has headroom at 440 V (32 kA), but at 500 V the 11.9 kA rating is the limit. Match the interrupting rating at your actual line voltage, not the headline number.
Thermal derate and power loss
The 16 A rating holds flat from 40 °C to 55 °C, then derates to 15 A from 60 °C to 70 °C. That's a clean thermal curve — no surprise drop at 50 °C like some breakers. Maximum power loss is 10.6 W, which matters for heat buildup in a dense panel.
Panel fit and physical integration
Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — standard 4-pole MCCB footprint for DIN-rail or panel-mount.
