T&R RB10 Resistor Box
The T&R RB10 resistor box is used in conjunction with a current injection unit when testing low impedance relays and trips, allowing finer control of the current.
 
The unit is designed for use with the 100ADM mk1-5 and 200ADM-P, but may be used with any suitable current source. The unit has eight resistance ranges with a maximum power dissipation of 50W for any one resistor.
 
T&R RB10 Resistor Box features:
0.5 ohms to 1666.5 ohms in 8 steps
Maximum current 0.2-10A
Improves current control into low impedance loads
Particularly suitable for solid state relays
Can be used as swamping impedance for non-linear loads
Thermal cutout
 
The RB10 is supplied in a robust aluminium case, and all connections are made by industry standard 4mm safety sockets.
 
Supplied with
Calibration certificate
Low current leads
