630 A MCCB with 187 kA interrupting — what the ratings mean for your panel
The 3VA2463-5HL32-0JH0: This MCCB carries a shunt trip (STL) auxiliary release as standard, plus 2 auxiliary switches and 1 trip alarm switch (HQ configuration). The integrated auxiliary trip is order code 3VA9688-0BL32. Maximum power loss is 162 W. Latching endurance is rated at 15,000 cycles.
DIN-rail integration and physical fit
Mounts on DIN rail (standard top-hat rail per EN 60715). Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 138 mm width means it occupies three 45 mm modular spaces — typical for a 3-pole MCCB in a SENTRON distribution board. Depth of 110 mm clears most standard enclosure gland plates; verify clearance for the shunt trip wiring and auxiliary cable exit at the bottom.
Auxiliary and trip options
The basic switch supplied is 3VA2463-5HL32-0AA0. The shunt trip (STL) design means a separate control voltage triggers the trip — useful for remote emergency-stop or undervoltage protection schemes. No undervoltage release fitted, no communication function, no phase-failure detection, no ground-fault monitoring. Trip indicator and voltage trigger are present.
