Siemens 3VA1 Series Molded Case Circuit Breaker, 250A Current, 690V ac Rated Voltage - 3VA1225-5EF32-0AA0

This moulded case circuit breaker provides three-pole line protection for electrical systems. Designed for use on AC and DC networks, it delivers thermal-magnetic overcurrent control with adjustable overload and short-circuit release settings. The device suits installations requiring a front-terminal connection and a Compact footprint while operating in ambient temperatures from -25°C to 70°C.

Features and Benefits:

• 55kA breaking capacity for high interrupting capability
• Type M tripping characteristic limits fault energy during short-circuit events
• Adjustable Ir 175A to 250A for tailored overload protection
• Front Terminal with nut keeper kit enables secure conductor fastening
• 800V insulation rating supports robust dielectric performance

Applications

• Suitable for protecting distribution panels in factories
• Used with motor control circuits requiring adjustable overloads
• Ideal for switchgear where high interrupting capacity is needed
• Can be used for DC supply protection up to 500V DC
• Suitable for installations demanding front-access terminations

What short-circuit making and breaking capabilities does it provide?

It offers Icm up to 187kA at 240V and Icu 55kA at 415V, with reduced values at higher voltages.

How is the thermal-magnetic protection configured for overload and short-circuit?

The L-trip Ir is adjustable between 175A and 250A and the I-trip Ii is settable from 1 250A to 2 500A.

What environmental and service-life characteristics are specified?

It operates between -25°C and 70°C, has a typical mechanical life of 20 000 cycles and electrical endurance up to 8 000 cycles at 380/415V.

Which connector types and conductor cross-sections are supported?

Front terminals accept flat-bar connections from 13 x 1 mm minimum to 25 x 8 mm maximum using a nut keeper kit.
