The adjustable overload trip range spans 1.5 A to 256 A, so you set the pickup to match the downstream load rather than swapping the breaker body. Breaking capacity hits 330 kA at 240 V and stays at 242 kA through 440 V, then drops to 187 kA at 500 V and 4.5 kA at 690 V — the high 240 V figure tells you this unit is built for high-fault utility feeds or transformer secondaries where available fault current is substantial.
The 160 A continuous rating at 70 °C means this breaker handles full load in a hot panel without forced cooling — useful for a packed switchboard or a sunny outdoor enclosure. The 4-pole configuration (three phases plus neutral) suits three-phase four-wire systems where neutral protection is required, common in North American 120/208 V or 277/480 V wye distribution. Communication function is built in — the 3VA2 platform supports PROFIBUS or PROFINET via a plug-in module, so the breaker reports status and trips into a control system without hardwired aux contacts alone.
Depth of 86 mm leaves room for rear-connected bus stabs or a cable entry gland behind the panel backplate.
Maximum power loss is 22.2 W at rated current. The 70 °C operating maximum is the breaker's ambient limit, not the enclosure interior; keep internal air temperature below that threshold.
