TRANSIENT CONNECTOR SM 4.21

The connector is brushed and greased, so only the handling of the connecting wires remains to be done at the installation site. Supplied in plastic bags. To facilitate installation, the SM2.25 connector has stainless steel springs that hold the connector halves open before tightening. Thanks to the cut-off top bar, the transition connectors SM2.21, SM2.25, and SM4.21 allow two copper branch wires of different cross-sectional areas to be connected to an aluminum main conductor with a single connector.
