Product details

The A9N60742 is a 4-pole miniature circuit breaker from the Schneider Acti9 C120 series, rated 100 A at 40 °C.

The 4-pole body occupies 12 x 9 mm pitches (108 mm wide). Tunnel-type terminals accept 1-50 mm² rigid or 1.5-35 mm² flexible cable; tighten to 3.5 N·m. The toggle handle is sealable in OFF or ON position with a 0.7 mm cable tie for lockout/tagout.

Durability and environmental ratings

Rated for 5000 electrical cycles and 20,000 mechanical cycles — enough for a distribution panel that sees infrequent switching; not a contactor replacement for daily cycling.

Frequently asked questions

How do I get current pricing and availability for A9N60742?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is the breaking capacity of A9N60742?

10 kA Icu at 230-400 V AC 50/60 Hz conforming to EN/IEC 60947-2. That is the maximum fault current it can safely interrupt at those voltages.

What compliance documentation does this brand provide for A9N60742?

The breaker is certified to EN/IEC 60947-2 (industrial MCB standard) and carries IP20 protection per IEC 60529. Tropicalisation class 2 per IEC 60068-1. Standard Schneider declarations for RoHS and REACH are available on request.
