FAQs
What mounting and clearance requirements apply to the 878BH when integrating it into existing control panels? The 878BH uses a surface-mount configuration with a round brass enclosure, designed for ordinary locations. Ensure adequate room for the 3.38 in length, width, and height, and provide proper cable entry points to maintain IP66 integrity. Use compatible Pauluhn TG toggle switch components and follow standard procedures for surface-mounted electrical boxes to optimize seal integrity and accessibility for maintenance.
The 878BH supports 10A/20A amperage and a 125 Vac / 250 Vac voltage rating, with a horsepower rating of 1.50 hp. This makes it suitable for common control circuits and small motor loads in industrial equipment. When designing a system, verify circuit protection and conductor sizing align with these ratings to ensure safe operation and avoid nuisance trips or overheating.
Yes. The enclosure carries an IP66 ingress protection rating and is intended for ordinary/non-hazardous locations, making it appropriate for outdoor and damp environments. Brass construction adds corrosion resistance, while the surface-mount design and round form factor support reliable performance in exposed areas such as outdoor panels and marine-adjacent equipment.
The 878BH is part of the Pauluhn TG family, featuring a three-way toggle switch. For retrofit or expansion, reference the Pauluhn TG catalog pages for compatible marine toggle switches and related accessories. Ensuring you use a TG-series switch that matches the voltage and amperage ratings will preserve enclosure integrity and electrical performance.
IP66 protection minimizes ingress-related failures due to dust and water exposure, reducing maintenance frequency and repair costs. Brass construction enhances corrosion resistance in challenging environments, extending service life and lowering replacement costs. Together, these features translate to lower total cost of ownership for outdoor, industrial, or marine control installations.
