Siemen circuit breaker code 5sq270 2ya50

A specific Siemens circuit breaker code!

The code "5SQ270 2YA50" is a Siemens circuit breaker designation, which breaks down into several components:

• "5SQ270" is the main code, which identifies the circuit breaker as a Siemens type 5SQ, with a current rating of 270 A.
• "2YA50" is the additional code, which specifies the trip unit and other features of the circuit breaker.

Here's a breakdown of the additional code:

• "2Y" indicates that the circuit breaker has a thermal-magnetic trip unit, which means it trips both thermally (due to overheating) and magnetically (due to excessive current).
• "A50" indicates that the trip unit has a setting of 50 A, which is the current at which the circuit breaker will trip.

So, in summary, the Siemens circuit breaker code "5SQ270 2YA50" refers to a 270 A, thermal-magnetic trip circuit breaker with a trip setting of 50 A.
