Product details

Three modular width units (each 18 mm) on DIN rail, 70 mm installation depth — fits standard SENTRON distribution boards and most third-party enclosures. Terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², which covers most final-circuit wiring sizes up to 4 mm² and still has headroom for a 10 mm² feed-through. Rated for any mounting position, ambient temperature range -20 to +45 °C, with IP20 protection once conductors are connected.

Approvals and environment

Rated for overvoltage category III, energy limiting class 3, and vibration resistance of 50 m/s² at 25 to 150 Hz per IEC 60068-2-6. Storage temperature range -40 to +75 °C covers most warehouse and transport conditions.

Frequently asked questions

What is the breaking capacity of 5SJ6313-7?

6 kA per both EN 60898 and IEC 60947-2 at 400 V AC. That is the standard breaking capacity for this SENTRON 5SJ6 series — suitable for most commercial final-subcircuit protection where fault levels are moderate.

How do I get pricing and availability for 5SJ6313-7?

Submit an RFQ. This part is sourced through independent distribution channels; current pricing and stock position are confirmed at quote time.

What wire sizes does 5SJ6313-7 accept?

Solid or stranded copper from 0.75 mm² up to 25 mm². That covers most final-circuit wiring up to 4 mm² and allows a 10 mm² feed-through if needed.

Does 5SJ6313-7 work on DC circuits?

The breaker is rated for AC/DC voltage type, with a maximum DC rated voltage of 60 V. For DC applications, verify the DC voltage does not exceed 60 V and consider the C-curve's magnetic trip threshold relative to your DC fault current profile.
