Product details

What you're looking at

Schneider GoPact G12E4A50 — a 4-pole moulded case circuit breaker (MCCB) from the GoPact MCCB 125 family, rated 50 A at 40 °C with a TM-D thermal-magnetic trip unit. The LI protection curve handles overload (thermal) and short-circuit (magnetic) faults.

Fixed-mount, backplate installation. Screw terminals front-top and front-bottom, 25 mm connection pitch. Neutral on the left, 4D protected poles (neutral fully rated at 1 x Ir). Overvoltage category III.

No official direct successor listed; the GoPact MCCB 125 family remains active.

Utilisation category A (non-delayed, no intentional short-time delay) — use it downstream of a current-limiting fuse or upstream breaker for selective coordination per IEC 60947-2 Annex H. Electrical endurance 8000 cycles at rated current; mechanical 30000 cycles.

Operating altitude 0–2000 m without derating, 2000–5000 m with derating.

Frequently asked questions

Where can I buy G12E4A50?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.

What is G12E4A50's breaking capacity?

15 kA at 380/415 V AC, utilisation category A, per EN/IEC 60947-2.

What trip unit does G12E4A50 use?

TM-D thermal-magnetic trip unit with LI protection: thermal overload (L) and magnetic short-circuit (I).

Is G12E4A50 suitable for isolation?

Yes, it is certified suitable for isolation per EN/IEC 60947-2. The toggle position gives positive indication of contact state.
