Product FAQs
7 answersWhat type of trip unit is equipped on the Siemens 3VA5340-7EC61-0AA0?
This breaker features a TM230 thermal-magnetic trip unit. It provides fixed long-time (thermal) overload protection and adjustable instantaneous (magnetic) short-circuit protection.
What is the breaking capacity class for the 3VA5340-7EC61-0AA0?
This model features a Class C breaking capacity, which delivers a high interrupting rating of 100kA at 480V and 200kA at 240V for demanding commercial and industrial applications.
How do I adjust the short-circuit protection on this breaker?
The TM230 trip unit has a fixed thermal rating of 400A, but the instantaneous magnetic (Ii) protection is adjustable. You can set the short-circuit trip point between 5 and 10 times the continuous current rating (2000A to 4000A) using the adjustment dial on the face of the breaker.
What are the physical dimensions of this 400A 3VA53 frame breaker?
Although it is a 2-pole breaker, it is built within a 3-pole frame footprint. It measures 5.4 inches wide, 9.8 inches high, and 5.4 inches deep.
Can the Siemens 3VA5340-7EC61-0AA0 be reverse fed?
Yes, Siemens 3VA5 thermal-magnetic circuit breakers are UL listed for reverse feed applications. This allows the breaker to be wired with the incoming line connections on either the top or bottom terminals.
Which enclosures are compatible with the 3VA5340-7EC61-0AA0?
This panel-mount breaker is designed to integrate seamlessly with Siemens 3VA panelboards and switchboards. It requires the appropriate mounting hardware or busbar adapters based on your specific enclosure setup.
Is this breaker suitable for direct current (DC) systems?
Yes, Siemens 3VA5 thermal-magnetic molded case circuit breakers are generally applicable on DC systems. For 250V DC systems, a 2-pole breaker is typically used with one pole wired to each leg of the supply circuit.
