Product details

It is built purely for isolation and switching — no overload or short-circuit protection electronics inside. The shunt trip (STL) release accepts 220–250 V DC or 208–277 V AC, and the auxiliary contact block carries 2 HQ auxiliary switches plus 1 trip alarm switch HQ. Front-terminal busbar connection, IP40 on the front face.

Dimensions: 130 mm height, 101.6 mm width, 70 mm depth — the 101.6 mm width is a standard 4-pole MCCB footprint, so it drops into existing 4-pole cutouts without rework. Front terminal busbar connection keeps wiring in the same plane as adjacent breakers.

Frequently asked questions

How do I get pricing and availability for 3VA1110-1AA42-0KH0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the closest functional alternative to 3VA1110-1AA42-0KH0?

The peer 3VA1110-5EE32-0JA0 is a 3-pole molded case circuit breaker (line protection) on the same 160 A frame with 100 A rating and shunt trip, but it includes overcurrent protection (TM220 release) and has a different auxiliary contact configuration — no trip alarm switch. It will not drop into a 4-pole panel without rewiring and does not switch the neutral. For a pure switch disconnector function, stick with the 4-pole 3VA1110-1AA42-0KH0.

Will 3VA1110-1AA42-0KH0 drop into a panel wired for 3VA1110-5EE32-0JA0?

No. The 3VA1110-5EE32-0JA0 is a 3-pole device (76.2 mm wide), while this is a 4-pole device (101.6 mm wide). The panel cutout and busbar arrangement would need to accommodate the extra pole. Also, the connection type differs: this uses busbar connection, the peer uses lug terminals.
