This Siemens SENTRON wire connector, model 3VA9132-0JF60, is an accessory for the 3VA5 125 circuit breaker series. It utilizes the TA2.5 terminal designation and is designed for connecting electrical conductors.
The connector supports copper and aluminum cables with cross-sections ranging from 1.5 mm² to 35 mm² according to IEC standards, and 14 AWG to 2 AWG according to UL standards. It has a permissible conductor temperature of 75°C when used according to UL 486A-486B.
Installation involves specific stripped lengths and tightening torques for secure connections. IEC specifications detail tightening torques for solid, stranded, and finely stranded copper cables, ranging from 2.8 Nm to 7 Nm depending on the conductor size. UL specifications provide tightening torques in lb-in for various copper cable types and sizes.
This accessory comes in a standard package of 2 units. It is compatible with Siemens 3VA5 125 circuit breakers, providing a reliable connection solution in electrical distribution systems.
It accepts stranded copper conductors from 1.5 to 35 mm² (IEC) and 14 to 2 AWG (UL), solid copper from 1.5 to 10 mm² (14 to 10 AWG), and finely stranded copper from 1.5 to 25 mm² (14 to 2 AWG). Aluminum conductors are also supported: solid 12-10 AWG and stranded 12-2 AWG.
The stripping lengths are 12 mm, 24 mm, and 39.5 mm (equivalent to 0.47 in, 0.9 in, and 1.55 in).
Tightening torques depend on conductor type and size: for solid copper 1.5 mm² it is 2.8 Nm, for 2.5-10 mm² it is 6.2 Nm, and for 16 mm² it is 7 Nm. For stranded copper, similar ranges apply: 1.5 mm² at 2.8 Nm, 2.5-10 mm² at 6.2 Nm, 16-35 mm² at 7 Nm. In imperial units, stranded copper 14-8 AWG uses 55 lb-in, 6-2 AWG uses 62 lb-in.
The permissible temperature of the connectable conductor is 75 °C, as per UL 486A-486B.
The standard package quantity is 2 units.
The terminal designation is TA2.5.
