Product details

The Schneider Electric G12E4A16 is a GoPact MCCB 125 molded-case circuit breaker, 4-pole, rated 16 A at 40 °C with a TM-D thermal-magnetic trip unit. It is certified as a disconnect switch per EN/IEC 60947-2, so it serves as both overcurrent protection and a visible-break isolation point.

The TM-D trip unit has a fixed thermal curve and a magnetic pickup around 10x In, so it's a general-purpose distribution breaker, not a motor-protective device. The 4D protected poles means all four poles have full thermal-magnetic protection — no solid-neutral pole here.

Mount it flat on the back, either horizontal or vertical; no DIN-rail clip on this one. At 18.7 W dissipation per pole, four poles pull about 75 W total — factor that into your enclosure thermal budget. The toggle handle gives manual on/off and trip indication.

Frequently asked questions

What is the breaking capacity of G12E4A16?

The G12E4A16 has a 15 kA breaking capacity at 380/415 V AC (performance level E).

What does the TM-D trip unit protect against?

The TM-D trip unit provides LI protection: thermal for overload (L) and magnetic for short-circuit (I), with a fixed thermal curve and magnetic pickup around 10x In.

Where can I buy G12E4A16?

The G12E4A16 is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What compliance standards does G12E4A16 meet?

The G12E4A16 complies with EN/IEC 60947-1, EN/IEC 60947-2, and EN/IEC 60947-2 Annex H, and is certified for isolation per EN/IEC 60947-2.
