The 3VA2163-6HL36-0KL0 carries a shunt trip (STL) auxiliary release and a 2+1+1 auxiliary switch configuration (2 auxiliary switches, 1 trip alarm, 1 electrical alarm), so it integrates into safety circuits or remote-trip schemes without a separate accessory stack.
Current rating and thermal performance
That means a panel running hot near the top of its 70 °C operating limit still carries the full 63 A without nuisance tripping. The adjustable thermal-magnetic trip range spans from 95 A minimum to 756 A maximum, giving the commissioning engineer room to tailor the instantaneous pickup to the load's inrush profile.
At 240 VAC it clears 242 kA; at 415 V and 440 V it holds 187 kA; at 500 V it still manages 121 kA. In a 400 V-class panel (the most common industrial distribution voltage), 187 kA SCCR gives ample headroom for transformer-fed main breakers and bus-riser protection.
The 86 mm depth (3.39 in) is shallow enough for shallow-profile wall-mount enclosures; the 105 mm width (4.13 in) matches the typical 3-pole mounting centers. No undervoltage release fitted from the factory — that's a field-install accessory if your safety circuit demands it.

Environmental limits and storage
The storage maximum of 80 °C is the handling limit — don't leave it in a hot truck or roofed warehouse in summer without checking the internal packaging. The operating minimum of -25 °C covers cold-start conditions in unheated switchrooms or outdoor enclosures in temperate climates.
