This plug and receptacle is technically known as the SI 32 (Israeli 16 A/250 V earthed)
This plug is unique to Israel and is incompatible with other sockets. It has three flat pins to form a Y-shape. The Type H plug is rated at 16 A but in practice the thin flat pins cause the plug to overheat when connecting large appliances. In 1989, the SI 32 was revised to use three round 4 mm pins in the same locations as the older standard. Sockets made since 1989 accept both flat and round pins in order to be compatible with both old and new plugs. This also allows the Type H socket to accommodate type C plugs which are used in Israel for non-grounded appliances. Older sockets, from about the 1970s, have both flat and round holes for "Live" and "Neutral" in order to accept both Type C and Type H plugs. As of 2008, older Type H sockets (which accept only old standard Type H plugs) were very rare in Israel.
