Vertiv WMBC208-EXM60K3BTK 208 V 60K Breaker | UPS Power Distribution

Protect upstream UPS distribution with a Vertiv breaker assembly built for controlled access and service discipline. The WMBC208-EXM60K3BTK is configured for 208 V EXM applications and combines three breakers with a Kirk key lockout approach to help limit unauthorized access during maintenance windows. In enterprise power rooms, the difference between standard distribution and controlled distribution is operational confidence. This assembly is intended for environments where service access must be managed, breaker handling must be deliberate, and uptime expectations are non-negotiable. It fits the kind of infrastructure where a lower-cost, generic panel is not enough because access control and system-specific compatibility matter. Use it to support UPS-connected loads that require a secure breaker interface and a clean fit within Vertiv EXM power architecture. The result is a distribution component that aligns with the discipline of data center operations: fewer surprises, tighter control, and a better match for critical infrastructure workflows.
