Product Launch, Siemens Tandem new BT Bolt-on Breakers

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).
