Product details

At 400 V AC rated voltage, this breaker handles 3-phase line-to-line circuits common across European 400/230 V networks.

Deployment context

Mounting position is unrestricted — vertical, horizontal, or inverted — which helps when panel layout is tight. The sealable design allows the panel builder to lock the toggle position after commissioning, preventing unauthorized reset during maintenance.

Temperature and environmental range

Rated for ambient operation from -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, tapering to 35% RH at 75 °C).

Frequently asked questions

How do I get current pricing and availability for 5SY6310-7?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ to confirm current pricing and availability at quote time.

What compliance documentation does the 5SY6310-7 carry?

Certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No.235. Halogen-free and silicon-free. The sealable toggle and IP20 rating are documented on the nameplate.

Will 5SY6310-7 drop into a panel specified around 5SY4101-7CV without rewiring?

Both are 3-pole SENTRON MCBs in the same 3-module-width footprint (54 mm), so the mechanical fit is identical. The 5SY6310-7 carries a C-curve and higher breaking capacities (6/15 kA vs the 5SY4101-7CV's ratings), so verify the trip characteristic and fault level match the panel design before substitution.
