Regal Rexnord
Switchgear
Regal Rexnord power control switchgear encompasses the integrated electrical distribution and control assemblies that manage the flow of utility and emergency power to critical building loads — including automatic transfer switches(ATS), bypass - isolation switches, circuit breakers, and control logic — all housed in NEMA - rated enclosures custom - configured for the specific electrical distribution requirements of the facility.Under the ASCO Power Technologies brand, our switchgear line is the industry standard for hospital essential electrical systems, data - center power distribution, water - treatment plant backup power, and any facility where reliable, code - compliant transfer of critical loads between utility and emergency sources is essential for life safety and business continuity.Specifying engineers choose ASCO switchgear for its UL 1008 listing, its ability to provide closed - transition(make - before -break) transfer for seamless load testing without power interruption, and its bypass - isolation features that allow automatic transfer switch maintenance without removing critical loads from emergency power protection.As the power - control backbone of the emergency and standby power system, ASCO switchgear represents the engineered reliability that facility owners and consulting engineers demand when power continuity is non - negotiable.

Trusted by Industry Leaders
UL 1008 Listed Automatic Transfer Switches
The definitive safety and performance standard for emergency and standby power transfer switches, providing the listing that is mandatory for NFPA 70(NEC) and NFPA 110 compliance.
Bypass - Isolation for Maintenance Without Load Interruption
A manual bypass switch and isolation mechanism that allows the ATS to be serviced or replaced while critical loads remain powered from either source — eliminating the downtime required for ATS maintenance.
Closed - Transition Transfer for Seamless Testing
The ability to parallel the utility and generator sources momentarily during retransfer, allowing load testing without the “blink” of an open - transition transfer — critical for data centers and facilities with sensitive electronic loads.
Custom - Configured Switchgear Lineups
Circuit breaker distribution sections, ATS sections, and control / metering sections assembled into a single, factory - wired, and tested switchgear lineup — reducing field installation time and ensuring integrated system performance.
Power Monitoring & Control Integration
Digital power meters, communication gateways(Modbus, BACnet, SNMP), and remote annunciator panels that provide facility operators with real - time status of source availability, switch position, and load levels.
Service - Entrance Rated Configurations
Switchgear rated for use as the main electrical service entrance, meeting the utility and code requirements for service - disconnect and overcurrent protection.
ASCO Switchgear in Hospital & Healthcare Emergency Power
Hospital essential electrical systems(life - safety, critical, and equipment branches) depend on ASCO switchgear to automatically transfer to emergency power within the 10 - second window required by NFPA 99 and the Joint Commission.The ASCO 7000 SERIES ATS and custom switchgear lineups are the most widely specified in North American healthcare, providing the contactor - based reliability, bypass - isolation serviceability, and the power - monitoring capabilities that hospital facility directors require.With over 100 years of power - switching innovation, ASCO’s healthcare switchgear solutions are designed, tested, and listed specifically for the unique requirements of hospital electrical distribution — a pedigree that engineering firms and hospital owners rely upon when specifying the power - control system that protects patients and critical medical procedures.
Switchgear for Data Centers, Water Treatment & Mission - Critical Industry
Data centers with 99.999 % uptime requirements, water - treatment plants whose pump outage can cause environmental violations, and pharmaceutical manufacturing facilities where process interruption means product loss — all depend on ASCO switchgear to manage their multiple power sources, including utility feeds, multiple generators, and UPS systems.Our switchgear lineups provide the custom distribution topology, fault - current ratings, and paralleling controls that these complex power systems require.ASCO’s closed - transition capability allows generators to be tested under load without risk of the momentary power interruption that can crash servers or disrupt sensitive process controls, making monthly generator testing a routine, risk - free exercise rather than a high - stakes operational gamble.
