Switch disconnector Spamel ŁK40-1.828OB2 40A 0-1 2-pole in enclosure

Spamel ŁK40-1.828OB2 is a 2-pole switch disconnector designed for manual isolation and load switching in low-voltage electrical installations. Rated for 40 A with clear 0–1 ON/OFF positions, this enclosed unit combines a compact footprint with a protective housing to simplify installation in distribution boards, machinery control panels, and service cabinets.

Advantages

The enclosed design protects the switch mechanism from dust and accidental contact, improving safety during operation and maintenance. A clear two-position handle provides unambiguous visual indication of circuit status. The unit’s compact two-pole configuration saves space compared with larger multi-pole assemblies and allows straightforward integration into existing electrical assemblies. Robust contacts and a stable mechanical actuator ensure reliable switching at the rated current.

Suitable for

• Isolation of single-phase and two-pole circuits up to 40 A
• Main switch or local disconnect in distribution boards
• Service panels for machinery and equipment
• Temporary and permanent installations requiring a compact enclosed disconnector

Key specifications

• Poles: 2-pole manual disconnector
• Rated current: 40 A
• Operating positions: 0 (OFF) and 1 (ON)
• Enclosure: protective enclosed housing for surface or panel mounting
• Operation: manual handle actuator with visual position indication
• Application: isolation and load switching in low-voltage circuits

How to use

Mount the enclosed switch disconnector in a suitable location inside a distribution board or on a service panel using appropriate fasteners and ensuring access for operation. Make electrical connections to the incoming and outgoing conductors according to applicable wiring standards and torque recommendations for secure, low-resistance terminations. Use the handle to switch between the 0 (OFF) and 1 (ON) positions only when the circuit conditions match the device ratings and relevant safety procedures are followed. Verify correct installation and operation before placing the circuit into regular service.

Usage recommendations

Use the switch disconnector for circuits within its rated current and voltage limits, and coordinate it with upstream protective devices as required. Regularly inspect terminals and enclosure for signs of loosening, corrosion, or damage, and perform maintenance with the supply isolated.
