Product description

The Siemens 5SY6310-6 is a 3-pole miniature circuit breaker featuring a B-curve tripping characteristic, designed for general-purpose overcurrent protection. It has a rated current of 10A, a breaking capacity of 6kA, and operates at up to 400V AC. The 70mm width allows for standard DIN rail mounting.

This circuit breaker is ideal for protecting resistive or mixed loads in residential and light commercial applications, such as lighting circuits or socket outlets where inrush currents are typically low. The B-curve provides rapid tripping for low-level overloads and short circuits.

Stanlo Automation, a veteran-owned surplus distributor, offers the Siemens 5SY6310-6. We are dedicated to providing reliable and cost-effective automation solutions to keep your operations running smoothly.

Frequently asked questions

What is the key difference between a B-curve and a C-curve breaker like the Siemens 5SY6310-6?

The Siemens 5SY6310-6 features a B-curve, which trips at 3-5 times its rated current. This is suitable for resistive loads. A C-curve breaker (like the 5SY6310-7) trips at 5-10 times its rated current, making it better for inductive loads with higher inrush currents.
