SIEMENS B360 Circuit Breaker BL 60A 3P 240V 10kA

SKU CH-8MBP-H5RY9

Three-pole bolt-on breaker rated 60 A at 240 V AC with a 10 kA interrupting capacity for Siemens P1 panelboards

  • 60 A three-pole protection for 240 V three-phase circuits
  • 10 kA interrupting rating clears heavy fault currents safely
  • Bolt-on mounting fits Siemens P1 panelboards directly
  • 125 A frame size supports 8 AWG minimum conductors
  • Compact 3.7 × 4.5 × 12.9 in profile saves panel space

Three-pole 60 A protection for Siemens P1 panels

This bolt-on miniature circuit breaker delivers 60 A of overcurrent protection across three phases at 240 V AC. It is built for Siemens P1 panelboards and load centres that accept the BL series frame. The toggle actuator provides clear on-off indication for maintenance staff.

10 kA interrupting rating at 240 V AC

The single figure that decides fit is the maximum AIR of 10 kA at 240 V AC. If the available fault current at the installation point exceeds this value, the breaker cannot safely clear a short circuit. Verify the system study before specifying this device.

Sustained 60 A carry within a 125 A frame

The 125 A frame size allows the breaker to carry its full 60 A rating continuously without nuisance tripping. Thermal-magnetic operation responds to prolonged overloads while the 10 kA magnetic trip handles severe faults. Lug terminals accept conductors down to 8 AWG for secure, low-resistance connections.

Questions about this item

What does the 60 A rating mean once the breaker is installed in a panel?

It means the breaker will carry up to 60 A continuously and trip if the current exceeds that value, protecting the downstream wiring in a three-phase circuit.

What does the 10 kA interrupting rating at 240 V AC cap in practice?

It caps the maximum prospective short-circuit current the breaker can safely interrupt to 10 kA on a 240 V AC supply.

What does the bolt-on mounting style need to fit in a Siemens P1 panelboard?

It needs a bolt-on bus stab in a Siemens P1 panelboard and accepts wire down to 8 AWG on its lug terminals.
