Emergency Operator Stations

Pilla emergency operator stations are UL Listed, code-compliant control stations for commercial and industrial emergency shut-down applications. Common uses include boiler shutdown switches, HVAC shut-down stations, emergency fuel shut-off stations, generator stop stations, and general emergency stop and emergency shut-off applications across commercial and industrial facilities.

ZOT Supply stocks the full Pilla line as an authorized distributor — surface-mount NEMA 4/4X/12 and NEMA 1 enclosures, flush wall-plate styles, and break-glass configurations to fit a wide range of installation requirements. Contact blocks are ordered separately for circuit flexibility, and most station styles are available with application-specific legends to meet code and AHJ requirements.
