HF115F-A-115-1ZS3A Mini 115V AC 16A Sealed PCB Relay Form 1C

The HF115F-A-115-1ZS3A is a compact, sealed miniature high-power relay designed for reliable switching in industrial control, automation, and PCB-based electrical systems. With a low-profile housing and robust electrical ratings, it is ideal for applications requiring higher load handling in a space-efficient design.

This relay features a Form 1C (SPDT) contact configuration, allowing a single control signal to switch between normally open and normally closed circuits. It operates with a 115V AC coil and a resistance of 8.1k , ensuring stable performance in AC-powered control environments.

With an enhanced switching capacity of up to 16A at 250VAC, this model is suitable for heavier load applications such as motors, pumps, HVAC systems, and industrial machinery. Its sealed construction protects internal contacts from dust, flux, and environmental contaminants, ensuring long-term reliability and consistent switching performance.

The relay is engineered with a 10mm creepage distance and 5kV dielectric strength between coil and contacts, providing strong electrical isolation and safe operation in high-voltage environments. Its compact footprint of 29.0 × 12.7 × 15.7 mm makes it ideal for high-density PCB layouts where space optimization is essential.
