The Reduced Silver series are suitable for applications where infrequent switching is specified. In such applications the degradation of the tip is minimal and therefore a higher volume of silver is unnecessary.
The RU80 is an economical alternative to the SU80 in applications where switching requirements are Uninterrupted such as with line contactors or telecommunication and power distribution systems. In such applications, contact wear is minimal and the amount of silver in the tip can be selectively reduced.
The RU80 features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. Due to the low switching nature of the contactor, servicing requirements are minimal, however spares are available. Mounting can be vertical or horizontal, when vertical the M8 contact studs should point upwards. If the requirement is for downwards orientation we can adjust the contactor to compensate for this.
