Notes: ¹Consult factory for life expectancy at other switching loads. ²This relay contains a bias magnet. Correct coil polarity must be observed. Models 5502 and 5504 susceptible to magnetic interaction due to bias internal magnet. ³Consists of 56V Zener diode and 1N4148 diode in series, connected in parallel with coil.
