Product Launch, Siemens Tandem new BT Bolt-on Breakers
November 29, 2022
Dual/Duplex BT Bolt-on Breakers: These new devices complement the BT and BQ breaker line of products.
Siemens Canada is pleased to announce the launch of dual/duplex BT bolt-on breakers. These space-saver duplex breakers combine two independent 1/2″ breaker poles in a common unit. The unit bolts onto one panelboard stab and requires one panel space and it is HACR rated. The BT series can be used anywhere a BL 1-pole will fit, up to 22kAIC.
Features & Benefits
Allows for single 15A or 20A tandem BT bolt-on breaker (B1515, B1515H, B2020, B2020H) to feed two 15A circuits or 20A circuits in place of 15A or 20A 1-pole BL breakers in a lighting panel or similar device.
For existing Siemens lighting panels, existing BL 15A or 20A 1-pole breakers can be replaced with tandem BT bolt-on breakers to free up space as needed. The quantity is limited to the available neutral connections in the panel.
P1-P3 lighting panels are improved in design to allow the following minimum number of Tandem BT bolt-on breakers (consult chart presented in fliers/product catalogue): 1. 18-circuit panels will allow at least 10 BT twins 2. 30-circuit panels will allow at least 20 BT twins 3. 42-, 54-, and 66-circuit panels will allow at least 30 BT twins
Older panels may have fewer neutral connection and will not allow as many BTs as shown. (primary restriction is the number of neutral positions available; must verify prior to installing in existing panels if there are enough neutral connections available).
