Product details

Siemens 5SY4132-5 — SENTRON 1-pole MCB, Characteristic A

Breaking capacity is rated at 10 kA per IEC/EN 60898-1 and 20 kA per IEC 60947-2 at 400 V AC, with a DC rating of 15 kA at 60 V per IEC 60947-2 and 5 kA per UL 1077. That dual-standard rating means the same unit can serve both IEC and UL-classified panels — the 20 kA figure under 60947-2 gives headroom for high-fault industrial environments where a standard 10 kA MCB might not coordinate. Rated operational voltage is 400 V AC (440 V max single- or multi-phase) and 72 V DC maximum.

The sealable design allows lockout/tagout compliance for isolation procedures.

Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Complies with IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No. 235.

Frequently asked questions

What is the breaking capacity of the 5SY4132-5?

The 5SY4132-5 is rated 10 kA per IEC/EN 60898-1, 20 kA per IEC 60947-2 at 400 V AC, 15 kA at 60 V DC per IEC 60947-2, and 5 kA per UL 1077.

Where can I buy the 5SY4132-5?

The 5SY4132-5 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.

What is the tripping characteristic of the 5SY4132-5?

The 5SY4132-5 uses characteristic A, meaning the magnetic trip operates at 2 to 3 times rated current — suited for protecting semiconductor circuits or long cable runs where fast clearing is required.

What compliance documentation does Siemens provide for the 5SY4132-5?

The 5SY4132-5 carries approvals per IEC/EN 60898-1, IEC/EN 60947-2, UL 1077, and CSA C22.2 No. 235. It is halogen-free and silicon-free.
