Type-tested low-voltage switchgear

SEN Plus is a steel-framed low-voltage power distribution and motor control switchboard for all applications. Thanks to its modular design, the SEN Plus range provides solutions up to 6300 A rated current. It is fully type-tested to IEC 61439-2 and certified by an independent third-party testing laboratory.

SEN Plus switchboards are built from incomer, motor feeder, and distribution sections. The assemblies can be implemented as single-front or back-to-back configurations. The basic structure is a module (H × W × D) 2200 × 600 × 600 mm, with an optional cable compartment enabling top or bottom cable entry.

The design meets internal segregation requirements up to Form 4. Form 4 means that each functional unit and its terminals are separated from each other and from the main busbars by partitions or barriers. Flexible cabling solutions are available, including top and bottom cabling, as well as dedicated cable compartments for each outgoing feeder unit.

The switchboard supports a wide range of incoming and feeder devices: fixed and withdrawable Emax2 and Emax3 air circuit breakers (ACBs), OS series switch-fuse disconnectors, Slimline fuse-switch disconnectors, OT series load break switches, Tmax XT moulded-case circuit breakers (MCCBs), and quick-change feeder modules in fully withdrawable versions. These feeder modules are compatible with industrial components tested and designed in accordance with IEC 60947, ensuring a seamless system solution.

Key benefits

• Rigid frame structure: Weld-free, galvanized, self-supporting robust construction consisting of three basic parts. No sharp edges.
• High operational safety: Short-circuit withstand, self-aligning busbar contacts ensure safe operation.
• Fast and easy cabling: Pre-defined busbar connection points or terminal strips.
• Durable surface treatment: Impact- and scratch-resistant powder coating, suitable for demanding environments.
• Optimised user experience: Door opening angle 135–185°, clear control and indication.
• Comprehensive digital solutions for power management, power distribution, and process control.
