Listing

The Pilla BSD120 is an emergency boiler shut-down station with a standard maintained 40mm red mushroom operator engraved "PULL TO RESET", mounted in a yellow NEMA 4/4X/12 enclosure with bold luminous "EMERGENCY BOILER SHUT-DOWN" legends. Contact blocks are ordered separately — the standard enclosure accepts 1-3 contact blocks. UL Listed and C-UL Listed.

Best for: Commercial and industrial boiler rooms requiring a standard code-compliant emergency shut-down station with maintained pull-to-reset operation.

The Standard Emergency Boiler Shut-Down Station

The BSD120 is the base model of the Pilla BSD120 series — the most widely specified emergency boiler shut-down station for commercial and industrial applications. The maintained operator latches in the actuated position and requires a deliberate pull to reset, ensuring the boiler cannot restart without intentional operator action. The yellow NEMA 4/4X/12 enclosure with bold luminous legends is immediately identifiable as an emergency shut-down point, satisfying code requirements for clearly identified boiler shut-down stations.

Common Applications

Commercial Boiler Rooms

Emergency shut-down for commercial heating boilers in hotels, schools, hospitals, and office buildings

Industrial Heating Plants

Emergency stop for industrial process boilers and steam generation equipment requiring maintained contact

Fuel Shut-Off Interlock

Interfaces to gas valve or fuel oil shut-off controls to de-energize burner on emergency actuation

Mechanical Room Safety

Clearly identified emergency stop point per local fire and mechanical codes

Multi-Circuit Shut-Down

Multiple contact blocks allow simultaneous shut-down of burner, fuel valve, and ventilation circuits

Code-Compliant Emergency Stop

Satisfies NFPA 85, local mechanical codes, and AHJ requirements for identified boiler shut-down stations

Contact Block Selection — PILNCCB vs. PILNOCB

Contact blocks are ordered separately. The PILNCCB (normally closed) opens the circuit when the button is pushed — the standard configuration for boiler shut-down where pushing breaks the control circuit. The PILNOCB (normally open) closes the circuit when pushed. Order the contact type that matches your control circuit design. Contact blocks accept up to 10 AWG wiring.

Frequently Asked Questions
What contact blocks does the BSD120 accept?
The BSD120 accepts Pilla PILNCCB (normally closed) and PILNOCB (normally open) contact blocks, ordered separately. The standard enclosure fits 1-3 contact blocks. Normally closed (PILNCCB) is the standard choice for boiler shut-down circuits where pushing the button opens the control circuit.
How is the BSD120 reset after actuation?
The BSD120 resets by pull to reset. The maintained mushroom operator stays in the latched position after being pushed and must be deliberately reset before the boiler control circuit can be re-energized.
What is the enclosure rating on the BSD120?
The BSD120 carries a NEMA 4/4X/12 enclosure rating. NEMA 4 and 4X provide protection against rain, splashing water, hose-directed water, and corrosion. NEMA 12 provides protection against dust and dripping non-corrosive liquids.
Does the BSD120 series include contact blocks?
No. All BSD120 series stations ship as the housing and operator assembly. Contact blocks are ordered separately. Use PILNCCB for normally closed contacts and PILNOCB for normally open contacts.
Why specify the BSD120 over the standard BSD120?
Standard base model The BSD120 is the standard maintained pull-to-reset boiler shut-down station suitable for most commercial and industrial applications.
