Engineered for industrial environments, the Siemens E23B060 is a 60A, 3-pole unit mount circuit breaker. It delivers consistent thermal-magnetic protection for 240V systems. This breaker installs into Siemens P1, P2, and P3 panelboards, as well as SB switchboards. It provides a seamless replacement solution for aging ITE infrastructure. For modern upgrades, this unit is replaced by the ED23B060. Delivering a 10kAIC rating at 240VAC, it includes fixed LI trip settings and is HACR rated.
What is the modern replacement for the legacy ITE E23B060?
The direct modern replacement is the Siemens ED23B060. It is a Sentron series ED2 frame breaker that matches the 60A, 3-pole, 240V, 10kAIC specifications and fits the same panelboards as the original E23B060.
How does the E23B060 mount into a panelboard?
The E23B060 features a bolt-on connection type. It is designed to bolt directly to the busbar in compatible Siemens P1, P2, and P3 panelboards, SB switchboards, and legacy ITE panelboards.
Do the standard lugs on the E23B060 accept aluminum wire?
Yes, the factory-installed lugs are rated for both copper and aluminum conductors ranging from 10 AWG to 1/0 AWG. Apply a listed oxide inhibitor when terminating aluminum wire.
What does the E2 frame designation mean for the E23B060?
The E2 frame indicates it is a standard-depth, molded-case circuit breaker from the legacy Siemens or ITE Sentron series. It shares physical dimensions with other E-frame breakers for consistent mounting and spacing in compatible enclosures.
How does the thermal-magnetic trip unit in the E23B060 operate?
The thermal-magnetic mechanism provides dual protection. A bimetallic strip responds to sustained overloads for long-time protection, while an electromagnetic coil instantly trips the breaker during severe short circuits.
Are the trip settings on the E23B060 adjustable?
No, the E23B060 features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
