Thomas & Betts 14RB-250F – Frequently Asked Questions
1) Will the Thomas & Betts 14RB-250F female disconnect fit a 1/4 inch spade tab?
Yes. The 14RB-250F is a 250 series female disconnect sized for a .250 x .032 inch tab, which is the standard quarter-inch blade you find on contactors, relays, fan motors and switches. If the male tab on your device measures 0.187 or 0.205 wide instead, this one will be loose and you need the matching series for that tab.
2) What wire size does the blue T&B 14RB-250F disconnect take?
It crimps onto 16 to 14 AWG conductor, and the blue vinyl insulation is the standard color code for that range. The insulation barrel accepts wire insulation up to 0.17 inch outside diameter, so heavily jacketed or double-insulated leads may not seat fully in the barrel even if the copper is the right gauge.
3) Can I use this disconnect on HVAC equipment that runs hot?
The 14RB-250F carries a 105 degree C temperature rating and a 600V rating, which covers typical furnace, air handler and condensing unit control wiring as well as line-voltage fan and contactor terminations. The vinyl sleeve is rated UL 94 V-0 for flammability. For anything above 105 C at the terminal, move to a nylon or high-temp insulated terminal.
4) Which crimp tool should I use on Stakon RB series insulated disconnects?
Thomas & Betts recommends the ERG4001 for these RB series insulated terminals. The WT145C, WT2000, WT112M and ERG4003 are also listed as application tools. Use an insulated-terminal crimp die, not a bare-lug nest, or the vinyl sleeve gets cut through.
5) How many Thomas & Betts 14RB-250F disconnects come in a pack and can I buy fewer?
They come 100 to the inner pack, with 500 to the outer carton, and the order multiple is 100. So you are buying in hundreds, not by the handful, which suits an MRO crib or a truck stock refill rather than a one-off repair.
6) Are these disconnects OK for marine or damp panel work?
The terminal body is brass with an electro tin-plated finish, which gives corrosion resistance and a low-resistance contact surface for damp or salt-air panels. The vinyl sleeve is not a seal, so in genuinely wet locations you still want heat shrink over the barrel or a sealed enclosure.
7) Is the T&B 14RB-250F RoHS compliant for a spec job?
Yes, it is RoHS compliant under exemption 06, which is the standard allowance covering lead as an alloying element in copper-base metals like the brass used for the terminal body.
8) What is the overall size of the 14RB-250F female disconnect?
Dimension A is 0.96 inch and dimension B is 0.29 inch, on 0.03 inch stock. That is a compact full-size 250 series body, so check clearance if you are stacking them on a crowded contactor or a tight terminal block where a flag or right-angle disconnect would seat better.
