Fuse disconnect switch KETO-00-3/F/HT 160A T500113002

Fuse disconnect switch – reliable installation protection

The KETO-00-3/F/HT 160A fuse disconnect switch is designed for safely disconnecting electrical circuits and protecting against overloads and short circuits. The construction based on the NH00 standard, combined with universal terminals, makes it a versatile solution for both installers and end users. The JEAN MUELLER brand product is characterized by solid workmanship and compliance with applicable standards.

Construction features and application

The KETO-00-3/F/HT disconnect switch is designed for baseplate mounting, which facilitates its integration with various electrical systems. Universal M8 x 16 / 2 x M5 terminals provide flexible cable connection, and the ability to connect cables from the top and bottom simplifies installation. Designed to work with NH00 type fuses with a rated current of up to 160A, it is perfect for protecting circuits with high power draw. The modern black switch handle increases comfort and improves the aesthetics of the installation.

Parameters and benefits

This disconnect switch stands out with its high technical parameters, which translate into its reliability and safety:

• Rated current Ie: 160A – provides effective protection for circuits with high power draw.
• Rated voltage Ue: 690V – allows use in high-voltage installations.
• Rated short-circuit withstand current Icc: 120kA (AC 500V) – guarantees resistance to the effects of short circuits.
• Conventional thermal current with fuses Ith: 160A – ensures stable operation under normal operating conditions.
• Conventional thermal current with fixed links: 250A - allows use without fuses in certain applications (limitations must be considered).
• Utilization category: AC-21B, AC-23B, DC-22B – confirms versatility in various types of circuits.
• Ambient temperature: -25°C to +70°C (taking into account the derating factor of the rated current) – enables operation in a wide temperature range.
• Degree of protection (front): IP20C - provides basic protection against accidental contact.

Manufactured from self-extinguishing materials (UL94) and with high dielectric strength (CTI 600) further enhance the safety of use. The disconnect switch meets the requirements of IEC/DIN EN60947-3, which guarantees its compliance with European quality and safety standards.
