Industry portfolio
The Nieaf-Smitt Industry portfolio contains 3 product ranges designed and manufactured for industrial applications;
Heavy duty power relays
Industrial plug-in power relay series, for heavy duty applications. Based on the unique C and D series design. Models for switching of resistive and/or inductive loads. We offer instantaneous, latching, timer relays, pulse relays and monitoring relays.
General purpose relays
These relays are designed to operate in AC and low voltage DC networks and switching of resistive loads.
We offer plug-in style instantaneous relays and also electronic timer relays and measuring & monitoring relays.
We offer plug-in style instantaneous relays and also electronic timer relays and measuring & monitoring relays.
Surge protection devices (SPD)
Surge protection devices will reduce the danger of electromagnetic disturbance (lightning) and overvoltages (surge). They protect the electrical installation of being damaged to a minimum.
