Shielded Insulating Contact Box (2 Way) for KYN61 Switchgear – 12kV/40.5kV
The Shielded Insulating Contact Box (2 Way) is a precision-engineered epoxy resin component specifically designed for KYN61-40.5 medium voltage switchgear. It houses and insulates the primary circuit contacts, providing reliable isolation between phases and to ground.
Rated for 12kV to 40.5kV with withstand voltage up to 95kV (power frequency) and 185kV (lightning impulse). This 2-way contact box accommodates two incoming/outgoing connections, making it suitable for circuit breaker compartments, PT bays, and feeder modules in KYN61 switchgear assemblies.

Q: Is this contact box a direct replacement for OEM KYN61 parts?
A: Yes. Dimensions match standard KYN61-40.5 specifications. We recommend ordering a sample for fitment verification first.
Q: What is the partial discharge level?
A: ≤3pC @ 1.1× rated voltage, with test report provided.
Q: Do you provide type test reports for utility bidding?
A: Yes. Routine tests (PD, withstand, impulse) included. Type test reports available upon NDA.
Q: What is the minimum order quantity?
A: Sample order (1-2 pcs) available. Bulk MOQ is 10-20 pcs depending on rating.
Q: Can this be used for other switchgear models besides KYN61?
A: It is optimized for KYN61 but can fit KYN28 and KYN44 with adapter brackets. Contact us with your drawing.
