Secucontrol STSA10028AF STS Test Block 10 Pole Dust Cover

SecuControl STSA10028AF is a 10-pole STS (Safety Test Switch) test block with a dust cover, designed to replace legacy knife switches with a finger-safe front disconnect and built-in status windows that let you confirm contact position at a glance. It offers banana jacks access for test leads, a Smart Dust Cover to protect the switching area, and is constructed from flame-rated UL94-V0 plastic. The unit supports a keyed safety system with an optional security lock, secondary injection, and customizable labeling to reduce misoperation and prevent forgotten disconnections. As a 10-pole configuration within SecuControl’s STS family (which covers 4–20 poles), it is intended for field equipment testing and safe isolation of circuits in power-system test setups.
