Construction Details
These ABB TEY breakers use a three-pole bolt-on configuration for compatible panelboard and electrical distribution applications.
The product family covers a wide range of branch and feeder requirements, beginning at 20A and extending through 100A.
Because bolt-on circuit breakers are equipment-specific, the exact panelboard, bus arrangement, voltage rating, available fault current, and mounting configuration should be confirmed before ordering.

Selecting the Correct Breaker
20A
Select TEY320 for the 20A three-pole configuration.
25A
Select TEY325 for the 25A three-pole configuration.
30A
Select TEY330 for the 30A three-pole configuration.
35A
Select TEY335 for the 35A three-pole configuration.
40A Compact
Select TEY340 for the listed 40A compact three-pole configuration.
45A
Select TEY345 for the 45A three-pole configuration.
50A
Select TEY350 for the 50A three-pole configuration.
60A
Select TEY360 for the 60A three-pole configuration.
100A
Select TEY3100 for the 100A three-pole configuration.
Three-Pole Configuration
These TEY breakers use a three-pole configuration intended for compatible multi-phase electrical systems where three conductors require coordinated switching and overcurrent protection.
The breaker should be selected as part of the complete electrical system design rather than from ampere rating alone.
Bolt-On Mounting
Secure Panel Connection
The TEY family uses bolt-on mounting for connection to compatible panelboard bus structures.
Equipment-Specific Fit
Bolt-on breakers must be matched to the exact compatible panelboard and bus configuration. Do not assume interchangeability with plug-in or unrelated breaker families.
