Circuit breaker enclosure Rittal SV 9342.210 — polyamide housing, 63 A, 20 × 215 mm

Rittal SV 9342.210 is a grey polyamide enclosure designed to house a single circuit breaker up to 63 A. The compact housing has a width of 20 mm and a height of 215 mm, providing insulation and mechanical protection for a mounted protective device in control panels and distribution boards. Supplied as a single lightweight unit (approx. 220 g), the enclosure is intended for straightforward installation where space-efficient, standardised mounting of one device is required.

Advantages

The polyamide construction offers electrical insulation and resistance to mechanical stress while keeping weight low. The slim 20 mm width allows dense arrangement of devices on mounting rails and saves panel space. The housing is compatible with bar systems that use 60 mm centre-to-centre spacing and accepts connections for round conductors or laminated copper bars, enabling flexible conductor routing and secure terminations.

Key specifications

How to use

Mount the enclosure on the intended rail or panel space and fit the circuit breaker into the housing according to the breaker manufacturer's instructions. Ensure the enclosure is aligned with the bar system if used, observing the 60 mm centre-to-centre spacing for proper integration. Make electrical connections with appropriate tools and torque settings for the chosen conductor type — either round conductors or laminated copper bars — and secure all terminations. Verify insulation, mechanical fit, and clearances before energising the circuit.

Recommendations

Use the housing in installations where a compact, insulated enclosure is needed for a single 63 A breaker. Confirm compatibility with the specific breaker model and follow applicable electrical standards for conductor sizing, torque values and spacing when connecting round conductors or laminated copper bars within a 60 mm bar system.
