  5. 5. New products Plug 2145 The need for additionally secured plugs in North America is increasing because home installations are to some extent unable to eliminate risks promptly. LEONI has therefore developed the 2-pin plug type 2145 in which a replaceable mini-protection for an additional power shutdown is included. The plug is approved by UL in conjunction with bulk cable SPT-2-R 18AWG. The protection is 2.5A at 125V. Plug 2160 The 2-pin type 2160 plug is based on the type 285 that has been successfully introduced in Europe. The distinctive feature is the pins that are provided with insulating sleeves used in Korea. The plug is specially designed for heavy power tools of the Korean market. Plug 380 The type 380 plug is the first LEONI 2-pin plug with protection contact to have been approved by the Thai approval authority. The plug is for applications of 250V and a load up to 16A. In addition to this plug there are two further plugs available for the market in Thailand.New approvalsLEONI Cable Xiamen LEONI SlowakiaThai plug 380C validated by EEI EU plug CW3191 now also a double insulated version with cap approved by KemaLEONI Cable Xiamen/LEONI Slowakia EU 282/2 plugs portfolio broadened withCustomer specific GD3A connector ENEC approved by Kema ■■ a double insulated version with cap ■■ H05BB-F 3G2.50 mm²LEONI Cable Xiamen/LEONI Cable Changzhou ■■ H05VV-F 3G2.50 mm²Perilex plug 415C approved as 4 and 5 pole ■■ H05RR-F 3G2.50 mm²plug by Kema ■■ H05RR-F 3G1.50 mm² ■■ H05RR-F 3G1.00 mm² ■■ H07BQ-F 3G2.50 mm² LEONI insider 5
