Integrator's Spec Recap
The Siemens 3VA2463-5KQ32-0HD0 is an IEC frame 630 molded-case circuit breaker in the 3VA2 series, 3-pole, with a breaking capacity class M rated at Icu=55kA @ 415V AC. The ETU860 electronic trip unit provides LSIG protection (long-time, short-time, instantaneous, ground fault) with an adjustable overload protection range Ir=250A...630A, short-circuit protection Isd=0.6..9x In, and Ii=1.5..9x In. Ground-fault protection is switchable up to 160%, with Ig=0.2...1 x In and tg=0.05-0.8s. The breaker includes a shunt trip (STL) rated 12-30V DC; 24V AC 50/60Hz, plus three auxiliary switches HQ. A nut keeper kit is included for secure mounting. This is a line-protection device, not a motor-protective breaker — the ETU860 is configured for cable and busbar protection with LSIG coordination curves.
Compliance & Documentation
As a Siemens 3VA2 series device, this breaker is designed to meet IEC 60947-2 for low-voltage switchgear and controlgear. Typical documentation includes a declaration of conformity, CE marking, and compliance with RoHS and REACH directives. Specific certification packages (UL, CSA) should be verified against the exact variant at time of order.
