KETO-000 Fuse Disconnector – a compact solution for installers and users

The KETO-000 fuse disconnector is part of the KETO series and is distinguished by its exceptionally narrow housing – only 53 mm wide. This feature allows two KETO-000 disconnectors to be mounted in the space occupied by one standard KETO-00, optimizing space utilization in the distribution board. Its compact dimensions and thoughtful design make it an ideal solution for both new installations and modernization of existing ones.

Construction and functionality

KETO-000 has been designed with ease of installation and safety in mind. Mounting on busbars with a thickness of 5 mm or 10 mm is done using a single screw connection, which significantly reduces installation time. The integrated holder for two microswitches allows easy signaling of the device position, and the ability to seal and lock provides additional protection against unauthorized access. Versions with drainage from the top and bottom are available, increasing flexibility in various installation configurations.

• Compact dimensions: 53 mm width saves space in the distribution board.
• Universal mounting: Possibility of mounting on busbars with a thickness of 5 mm or 10 mm.
• Status indication: Integrated holder for microswitches to signal the device position.
• Safety: Possibility of sealing and locking the device.
• Flexibility: Versions available with drainage from the top and bottom.
• Compatibility: Compatible with labeling systems (e.g. Phoenix UCTM) and other devices from the KETO-00 series.

Parameters and application

The KETO-000 disconnector is characterized by a rated current of 125 A and a utilization category of AC-22B/500 V. The rated conditional short-circuit current is 80 kA, which ensures effective protection of the installation against the effects of overloads and short circuits. It is intended for protecting electrical circuits in residential, commercial and industrial buildings. F50 lift terminals allow connection of cables with a cross-section of 1.5 - 50 mm², which provides a wide range of applications in various types of electrical installations. The degree of protection IP30 (from the front) guarantees protection against accidental contact, and IP10 with the cover open provides basic protection against solid objects. The device operates at an ambient temperature of -25°C to +70°C, allowing it to be used in harsh environmental conditions.
